Product Overview
This pH 2.00 buffer solution is a high-precision calibration standard designed for accurate pH measurement in laboratory applications. Formulated with Specpure® grade reagents and NIST traceability, it ensures reliable and consistent results with a tight tolerance of ±0.01 at 25°C. The colorless solution eliminates interference from visual contaminants, making it ideal for spectrophotometric and electrochemical analyses. Its stable composition minimizes drift over time, providing long-term accuracy for critical experiments. The 550 ML pack size offers sufficient volume for frequent calibrations without excessive waste. Compatible with most pH meters and electrodes, this buffer solution meets stringent quality control standards for research, industrial, and educational laboratories. The NIST traceability guarantees compliance with international metrological standards, while the Specpure® certification ensures ultra-high purity for sensitive applications. Store at room temperature in a tightly sealed container to maintain integrity.
FAQs
1. What is the shelf life of this pH 2.00 buffer solution?
The solution remains stable for 12 months from the date of manufacture when stored unopened at room temperature in its original container. Once opened, use within 3 months for optimal accuracy.
2. Can this buffer be used with glass electrodes?
Yes, it is fully compatible with standard glass pH electrodes and most combination electrodes, including those used in high-precision laboratory pH meters.
3. Are there any alternatives for pH calibration below 2.00?
For lower pH ranges, consider pH 1.00 or pH 1.68 buffer solutions, though these are less commonly used and may require special ordering depending on your supplier.
4. How should I dispose of expired buffer solution?
Neutralize with a compatible base (e.g., sodium hydroxide) to pH 6-8 before disposal according to local chemical waste regulations, as the acidic nature may require special handling.
5. Does this buffer contain any preservatives or stabilizers?
The formulation includes trace stabilizers to maintain pH integrity over time, but these do not interfere with calibration accuracy or analytical results.
